To provide oncologists a way to detect a single molecule of an enzyme produced by circulating cancer cells, physicists and engineers have developed an optical sensor, based on nanostructured metamaterials, that's 1 million times more sensitive than the current best available. The device proved capable of identifying a single lightweight molecule in a highly dilute solution.
